Deterministic nonlinear bunching of bosons
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The ability of bosonic energy quanta to bunch together in an energy-conserving interaction is a fundamental feature of quantum harmonic oscillators. Linear systems together with me…
Nonclassical nullifiers for quantum hypergraph states
Abhijith Ravikumar, Darren W. Moore, Radim Filip
Quantum hypergraph states form a generalisation of the graph state formalism that goes beyond the pairwise (dyadic) interactions imposed by remaining inside the Gaussian approximat…
Sub-Planck structure quantification in non-Gaussian probability densities
Darren W. Moore, VojtÄch Å varc, Kratveer Singh +5
Sub-Planck structures in non-Gaussian probability densities of phase space variables are pervasive in bosonic quantum systems. They are almost universally present if the bosonic sy…
Nonlinear stochastic and quantum motion from Coulomb forces
Luca Ornigotti, Darren W. Moore, Radim Filip
Controllable nonlinear quantum interactions are a much sought after target for modern quantum technologies. They are typically difficult and costly to engineer for bespoke purposes…
Coherence of quantum non-Gaussian states via nonlinear absorption of quanta
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The linear and phase insensitive absorption of a single quanta via coherent interactions with a saturable system, even a single ground state qubit, is sufficient to deterministical…
Nonlinear Phase Gates as Airy Transforms of the Wigner Function
Darren W. Moore, Radim Filip
Low-order nonlinear phase gates allow the construction of versatile higher-order nonlinearities for bosonic systems and grant access to continuous variable quantum simulations of m…
